The berries were identified as huckleberries, so my assumption was that it was an evergreen huckleberry variety since they were sourced locally. I purchased my plants mail order from a nursery in Oregon, so I’m pretty sure that is what I have in hand.
I think I read that the usda hardiness zone was a minimum of 7. With that said, I have four rabbiteye blueberry bushes that have the same zone minimum and they fruit well every year despite winter temperatures that fall to -5F or lower. I guess there is I only one way to find out for sure.
